Answer:
A quantitative form of Joule's law is that the heat evolved per second, or the electric power loss, P, equals the current I squared times the resistance R, or P = I2R. The power P has units of watts, or joules per second, when the current is expressed in amperes and the resistance in ohms....

Answer:
Joule's Law
He said that amount of electrical energy expended in a circuit is equal to the square of the current, times the resistance of the circuit, times the amount of time it was on.
...
Finally, we can combine Joule's law with Ohm's law and get a couple of other useful equations for power.
